It's not the flowers that make this plant so colourful, it's actually the magenta bracts. ... The bracts can be seen in all shades of pink and purple, and also red, yellow, white, salmon and orange. This is Grenada's national flower. Bougainvillea has been successfully grown outside in very sheltered areas in the UK 
Bougainvillea is a genus of thorny ornamental vines, bushes, and trees with flower-like spring leaves near its flowers. Different authors accept between four and 18 species in the genus.
